The swelling and phase stability of neutron-irradiated Fe-Cr-Mn and Fe-Cr-Ni alloys are compared in the range 420 to 600/sup 0/C. While the behavior of the two alloy systems exhibits many similarities, that of the Fe-Cr-Mn system is more complex, involving a higher level of phase instabilities. However, the sensitivity of radiation-induced density changes to composition is less in the Fe-Cr-Mn system. In the Fe-Cr-Mn system there are three major components of density change, namely void growth, ferrite formation and lattice parameter changes of the retained austenite; whereas void swelling is the only major component of density change in the Fe-Cr-Ni system.
